BUILDING AND CAR DOOR.

, Specification of Letters Patent.

Patented July 18. 1911.

Application inea April i3, i911. serial No. 620,760.

To all '1o/tom it may concern.;

Be it known that l. Eowwno (l. Sermon- Dnn, a citizen of the U'nited States` residing at tlintonville. inthe county ot Waupaca I and State ot' lViscons-in. have invented certain new and useful Improvements in luilding' and Car Doors, of which the t'ollowingjr is a specification. f

This invention relates to that class ot' doors which are Slidable across and away from the door opening; and it is the Yobject ot' the invention to provide a door ot' this kind lwhich is in two :sections` the Vsame beingr so mounted that either one or both sections can be slid into open and closed position.

The invention also. has for its object to provide improved supporting means for the door sections, together with an improved i fastening therefor.

Wlith these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being' had to the accompanying drawings forming' a part ot' this specification, in which drawings- Figure 1 is an elevation ofthe door in closed position. Fig, 2 is a similar view showinglr one ot the door sections open. Fie'. 3 is an elevation .showingr both door sections open. Figs. 4, 5 and b' are vertical sec`- tions on the lilies 4 4, 5-5 and (S-(, respectively, of Fig. 3.

Referring specifically to the drawings, l0 denotes one of the side walls ot a* 'freight car to which the door and the parts associated therewith, which are the subject ot the present invention, are applied. 'lhe doorl is in two sections which are indicated at ll and l2, respectively; At the top and bot-tom ot the door opening are stationary therebetween is a sliding track 15, the lengt h ot these tracks being' substantially twice the. width ot' the door sections. Theuppcr door section is supported by the tracks lit and 15, and said track 15 and the track lllsnpport the lower door section.

The sliding;- middle track l5, as shown in a channel bar lo, and two strips 17 and 1S ot' different, widths, all rivetedor otherwise 'lhe track is so positioned that the flanges ot' the channel bar extend horizontally and outwardly, the top flange being indicated at, 1f) and the bottoni i being rigidly mounted on the wall 10, two

on one side of the door opening, and the .other one on the other side thereof. Two oi these brackets are located close to the door opening'. and the other one is spaced theret'rom a distance equal to Substantially the width ot' the door opening. in view ot which the track will always be in engagei'iien't with at least two ot' the brackets.

To the top of the upper door section 11 are secured hangers "22 which engage the top track 13. and to the bottom of `said door section are secured slides which engage the sliding: middle track 15, said slides beiner shaped to hook over the top flange 19 of Said track. To the top of the -lower door section l2 are secured hangers Q4 which ci.- rae'e the bottom flange 20 ot the sliding middle track l5', and said lower door section is supported at its bottom on the track 14 by slides 25. 'lhe hangers and slides herein described are suitably shaped to prevent the-,door from falling forwardly ott' the tracks. At the latch end Aotl the track 15, the flanges lt) and Q0 thereof have bends 2G which prevent the door sections .from leaving the track at this end. ln the-path of the other end of the, track is a stop 9.7 to limit the movement ot' the track in that direction. rlljieniovement. ot the door sections to open position is limited. by stops 28 cured to the wall l0. 4

The l'orward end of the sliding middle track carries a pivote-d hasp 29 which is eneaeeable with a staple 30 located adjacent to the latch end ot the door opening. A slidingr latch pin 3l is provided -t'or securineA the hasp over the staple. said latch pin beine' slidably mounted adjacent to the staple by i'neans ot a bolt 32 secured to the car wallv` and passing Ithrough a slot 33 in the pin. By this construction therpin is prevented -from getting` lost and it is always ready tor use. The hasp Q9 lies inthe channel et the track t5, and its top and bottom edges are notched as indicated at 84. to receive the slide 23 and the hanger 24 at the forward end ,of the two door sections as shown in Fig. l, whereby said sections are the track is slidablfsipported locked in closed position when the hasp is l engaged with the staple. l ly the construction herein described, it l is possible to open either one or both door sections, and also to slide the track l5 enM tirely out of the doorway. Fig. 1 shows both door sections closed and locked. The middle track l5 has been slid torwardly and locked by the hasp and sta-ple, and the two door sections are locked by the engagement the parts 23 and 2li with the notches -'l ot the hasp. rl`he door sections cannot be the hasp 1s released and swung opened until discngage the parts 2B and Q-l. y

outwardly to Fig. 2 shows the top door section open and the bottom door section'closed, The parts are placed Ain this position by releasing the hasp. and swinging the same outwardly sut ficient to release the part 23, atter which the k top door section can be slid to open position. The hasp is then replaced into locking position so that the part 24 engages the bottom notch. The track remains in position extending across thedoorway, and it is locked in this position as before by means of the hasp and staple, the latter also locking the bottom door section as already described. lit the bottom door section is to be opened also, it is released by disengaging the hasp, after which it may be slid open as shown I in Fig. 3, and the track '15 may then also be slid away 'from the door opening to leave the same entirely unobstructed as shown. if desired, the two door sections may also be partly opened, the track l5 in this position of the doors being extended across the doori way and looked by the hasp and staple, as in Fig. l.

l claim:

l. car door comprising upper and lower sliding sections, stationary top and bottom tracks, a slidable middle track, the upper door section being supported by the top track and the lower door section beingV supported by the bottom track, and both of said door scctioifis also having slicing engiyagge4 l Y n osano? l ment with the middle track, and I`means for locking the middle track. i

2. A car door comprising upper and lower sliding sections, stationary top and bottom tracks, a sliding middle track adapted to be extended across the doorway, and to be slid outwardly therefrom, and means for locking vthe slidingtrack in the tirstementioned position, the upper door sectionbeing supported by the top track and the lower door tion being supported by the bottom track, i

and both of said door sections having a sliding engagement with. the middle track.

2%. A carV door comprisinglupperand lower sliding sections, stationary top and bottom tracks. a sliding middle track, the upper door section being supported by the top track and the lower door section being sup ported by the bottom track, and both ot said door sections having a sliding engagementwith the middle track, a pivoted hasp carried by the middle track, the upper and lower edges of the hasp being notched, a f

staple with which said hasp is engageable for locking the middle track, and means on the door sections engageable with the aforesaid notches whereby the door sections are locked.

4. A car door comprising upper and 'lower sliding sections, stationary top and bottom tracks, a sliding middle track, said middle track having top and bottom horizontal flanges, guide members carried by the door sections and engageable with said flanges, a pivoted hasp carried by the middle track, the upper and lower edges of said hasp being notched to receive the guide members when the door sections are in closed posi-A tion, and means 'for locking the liasp.

ln testimony whereof l affix my signature in presence ot two witnesses.
